Pressure gauge for Intex sand filter

[SunnyBama]

I think I need a new pressure gauge for my sand filter; the gauge never moves. It will register 0 with the pump off but when the pump is on it never goes above 5. It's the gauge that originally came with the system. Given the fact that Intex has proprietary sizing on all of their equipment, I am wondering if the gauges sold on the tftest kits site will work. Has anyone here used one of these gauges on an Intex pool?

If you turn off the pump, shut off the valves and unscrew the pressure gauge you should be able to see if it is a 1/4" or 1/2" shaft. I believe 1/4" is the standard size.

Yes, I got one. I had to get a bushing at the hardware store, seen below, to adapt it to fit the Intex filter.

My tftest filter only shows 5-6 lbs pressure after a backwash, so your Intex gauge may not be that far off. But it's a nice, cheap upgrade anyway.

Thanks for the info! I was afraid if I got one and it didn't fit, I wouldn't know how to make it fit. I see that it is a simple fix!

Yeah, it was less than $2. Just take your old and new gauges with you and ask a clerk to help you find something to make it fit.

I've replaced my Intex gauge with this one:

You will need an 1/8" MNPT X 1/4" FNPT adapter, as shown in the pic posted by jeffchap.

The gauge is very good quality, and much easier to read than the original.

BTW- my clean pressure is about 9-10psi.

If you decide to take both gauges with you to the hardware store be sure to isolate the filter so it doesn't drain the pool through the open pressure port.
